Wouldn't it be more efficient to use Etags and/or If-Modified-Since and let the server issue a "304 Not Modified" response? HTTP has built-in methods to help clients avoid downloading duplicate files. (In theory, the server could issue this response without even opening the file.)
Pardon me if this has been covered in one of the recent threads -- after a while they got so long that I gave up reading them.
